Epicardial mapping and ablation via a subxiphoid percutaneous approach
- Klinika kardiologie IKEM, Praha
Catheter ablation is an effective method for the treatment of cardiac arrhythmias. In some patients, the arrhythmogenic substrate can be located on the epicardial aspect of the cardiac chambers and may be inaccessible from the endocardium. Therefore, percutaneous epicardial access to the pericardium has been introduced. Currently, it is used for patients in whom endocardial ablation has failed or in whom imaging studies or ECG characteristics suggest the presence of an epicardial substrate. Other indications include specific myocardial diseases, such as arrhythmogenic cardiomyopathy and Brugada syndrome. The aim of our paper is to review current techniques and potential complications associated with percutaneous epicardial mapping and ablation. Additionally, a brief analysis of a patient cohort from our center is presented.
